To all whom it may concern.:

Beit known that I, ALFRED STELL, a subject of the King of Great Britain,and a resident of Green Hill, Steeton,near Keighley,

in the county of York, En land," have 1n-` vented certain new and usefuImprovements in Bearings for Spinnin -Machine Spindles,

of which the following (I with the accompanying sheets of drawings,

In the mounting of spindles or parts in connection therewith intheseveral classes of spinning-machines used in the production of yarns orthreads of fibrous substances x5 many devices have been employed for re-2 5 which the antifriction ball-bearings are mounted and the axes of theseveral spindles. In other Words, while it is almost a mechanicalimpossibility to mount the whole series of s inning-machine spindles tooperate with 3o their axes exactly in the vertical-*plane it is alsoalmost a mechanical impossibility to make thesupports, and consequentlythe ball-races, to be in the horizontal plane, with the result thatsince the spindles will not thus 3 5 rotate in a plane parallel withthat of the ball-races the benefit or utility of such antifrictionball-bearings is considerably reduced.

To obviat these disadvantages is the object of the p esent invention,and this is ac-` 4o complished by arranging the parts in such mannerthat the ball-races may be moved by the actions or weight of thespindles or parts which they support, so that said ball-races occupy atall times positions at right angles to the axis of said splndles orparts or a position parallel with t eir plane of rotation.

In the accompanying drawings,`which are illustrative of my invention,Figure 1 is an elevation of a dead-spindle with its hollow' or rotaryspindle mounted upon ball-bearings constructed in. accordance withmyinvention. Fi 2 is a view similar to Fig. 1, but ori-an en arged scaleand showing only so much of the structure as is necessary to in- 'dicatethe present invention, lsaid structure including the dead. and rotary orhollow spinj escription, together dles and the supporting structure, thespindles being shown as moved out of the vertical plane. l

Figs. 3 and 4 are views similar to Fig. 2, but showing modifications inthe form of certain of the parts. Fig, 5 is a sectional view taken onthe lineOD of Fig. 2. Figs. 2, 3, 4, and '5 are drawn to the same scale.

Similar reference characters indicate similar parts in all of the views.

The rail which supports the dead-spindle is indicated at G, while thatknown as the lifter-rail is shown at K.

' Referring particularly to Figs( .1 and 2, p designates'thecontainingmember or receptacle, having the inner surface a of its basepart formed convex, as shown. the ball-race member, which rests on thesurface a, the upper surface of said member a--being substantially flatand forming the ball-su porting portion of the raceway for` the seriesof balls b.

d indicates the hollow or rotary spindle, mounted on the dead-spindle cand adapted to be driven by the pulley s. Mounted on the spindle d isasleeve lc, in the lower surface of which is located the up er portion ofthe balla. designates raceway, the lateral ba l-retaining walls beingdesignated as e and f.

As shown, the member a. and sleevel 7c are loosely mounted within thereceptacle p for a purpose hereinafter set forth andare rev tainedtherein by means `of, a s ring-clip device rm., mounted within asuitabll cess formed in vsaid rece tacle.l The lower edge s of the'ulley s, w ich overhangs the whole bearing fdr affording protection aainst the entrance of most foreign matter or dirt, is of such sizediametrically as to lit loosely over the. outer face of the receptaclep. By this arrangement the spindled and the parts carried thereby,together with the member a, are maintained in position at right anglesto the axis of the spindlecby the weight ofthe superimposed parts andthe inabillty of the e annular relOO erefore beunderstood that while thespindle c is vertical the `b all-bearing structure will be substantiallycentrally located within the re- -ceptacle p.` As such Vtrue vertical isnotretained by the spindle c during the spinning operation, theinclinationsfrom such true-I vertical are overcome by the loose mountingof the ball-'retaining parts within the receptacle p in connection withthe convex surface a, which permits the memberc to rock on its' seat ina manner to retain the parallel- I I'o ism between it and the sleeve 7c,so that what,- I antifrictiomballs mounted upon the upper 5 5 eververtical position the 'spindle' c may as sume durin Ithe operation theball-retaining, structure will retain its position relative to thespindle c-viz., with 'the upper face of the member a, in position atright angles to the axis of the spindlec. These variations are shownbycomparing Figs. 1 and 2 of the drawings, Fig. 1 showing the spindle-cvertical, its axis-being represented in Fig. 2 by the line y y, While Fi2 shows the Vparts in the position assume by -them when the spindle c isout of such vertical position. (Indicated bythe dotted line Thevariation in position of the u per surface of the member a is similarlys own by the dotted lines vfvandwwinFigZ. l

Fig'. 3 differs from Fi 2 in showing the outer lateral wallfor the allsb as formed on the member a instead of on sleeve lc, such Wall in Fig. 3being indicated at j" the structure being suchthatthe wall extends frombelow instead of from above, as shown in l Fig. 5.

In the structure shown in Fig. 4 thewallf or f is omitted, the member aand sleeve c being formed as shown in Figs. 1 and 3, respectively, andthe outer lateral wall for the balls is provided by the separate memberhin the form of a ring; l

These modifications in structure do not,

however, affect the operation as describedin Fig. 2, they indicatingmerely different ways in which the balls may be retained in positionwithout modifying the relationship of member a and its convexsupporting-surface. v

' The. engagement between the arts d, k, and s may be effected in anypre erred manner, as by securing the pulley s and sleeve 7c on thespindle d by a drive fit.

In the different structures shown the parts which support the balls andretain them in position may readily be made of hardened steel or othermetal andare so mounted that they may rotate lfreely and therefore offerlittle resistance to the rotation of the balls.

Such being the nature vand object of my said invention, what I claimis* 1. An improved spindle-bearing comprising an outer receptacle orcontaining member,- aball-race member loosely mounted therein and havinga substantially flat upper surface, one of said members havinga convexface to permit the ball-race member to rock, and

surface of said ball-race member, substantially as specified.l

2. An improved spindle-bearing comprising an outer receptacle orcontainingv member, a ballrace member loosely mounted therein and havina substantially fiat upper surface, one of sai members having a convexface to permit the ball-face member to rock, antifriction-ballsmounted'on the upper surface vof said ball-race member, and acircularwall or ring for retainin Atheballs in a lateral d1- y rection,substantial y as herein specified.

3. In .a bearing or a hollow spindle, an

outer receptacle having the upper surface of 'its base part of a convexform, a ball-race mounted on said convex surface, antifrictionballsmountedfon said ball-race, and a circular retainer for saidantifriction-balls, substantiallyas herein specified. l

4. In a bearing for a hollowr spindle, an outer receptacle having theupper surface of its base part. of a convex form, a ball-race mounted onsaid convex surface, antifrictionballs mounted on said ball-race, and acircular retainery for said antifriction-balls, said retainer having aflange near its axis to form a lateral stay for the balls,'substantially as herein specified. y

5. In a bearing for a hollow spindle, an outer receptacle having theupper surface of its base part vof a convex form, a ball-race mounted onsaid convex surface, said ballrace having a flange encircling its outeredge to retain the balls laterally, antifriction-balls mounted on saidball-race, and a circular retainer for said antifriction-b alls,substantially as herein specified.

6. In a-bearing for a hollow spindle, an

.- youter receptacle having the upper surface of its base part of aconvex form, a ball-race mounted on said convex surface',antifrictionballs mounted on said'ball-race, a circular retainer forsaid antifriction-balls, ahollow spindle, a relatively stationaryspindle, and a s ring-clip taking into a groove formed on t e innersurface of the outer receptacle, substantially as herein specified.
